:DISPlay:GRADing:TIME
Syntax :DISPlay:GRADing:TIME <time>
:DISPlay:GRADing:TIME?
Description
Set or query the persistence time. The default unit is s.
Parameter
Name
Type
Range
Default
<time> Discrete {MIN|0.1|0.2|0.5|1|5|10|INFinite} MIN
Explanation  MIN: set the persistence time to its minimum to view the waveform changing in high
refresh rate.
 Specific Values: set the persistence time to one of the values listed above to observe
glitch that changes relatively slowly or glitch with low occurrence probability.
 INFinite: in this mode, the oscilloscope displays the newly acquired waveform
without clearing the waveform formerly acquired. It can be used to measure noise
and jitter as well as capture incidental events.
Return
Format
The query returns MIN, 0.1, 0.2, 0.5, 1, 5, 10, or INF.
Example
:DISPlay:GRADing:TIME 0.1 /*Set the persistence time to 0.1s*/
:DISPlay:GRADing:TIME? /*The query returns 0.1*/
:DISPlay:WBRightness
Syntax :DISPlay:WBRightness <time>
:DISPlay:WBRightness?
Description Set or query the waveform brightness.
Parameter
Name
Type

The query returns an integer between 0 and 100.
Example
:DISPlay:WBRightness 50 /*Set the waveform brightness to 50%*/
